Dissector bug, protocol AMQP

I'm seeing this error in Wireshark - 3.2.5 (v3.2.5-0-ged20ddea8138) - on Windows 10 x64.

The AMQP messages are coming from an Apache QPID server - I was using Wireshark to diagnose why my receiver process wasn't reporting any messages so this may be related.

Any suggestions about ways forward?
